WHAT IS AN ECOSYSTEM?
An ecosystem is made up of living and non-living things which work together to make a balanced system. Ecosystems have no particular size. They can be as large as a rainforest or a lake, or as small as a bush or a puddle. The biggest ecosystem on planet Earth is Earth itself.
Ecosystems can be aquatic or terrestrial. They can also be man-made.
